## Overview

The WWZMDiB 4 Digit 7 Segment Digital Tube LED Display Board is a compact, red-highlighted display module powered by the TM1637 driver IC. It supports 4-digit numeric and letter display with 8-level adjustable brightness, operates on 3.3V or 5V DC, and requires only two signal lines for MCU control, making it an ideal, easy-to-integrate solution for Arduino and other microcontroller projects.

## Description

Display device is 4-digit yang red digital tubeDigital tube 8-level grayscale adjustableWorking Voltage: 3.3V / 5v DCWorking Current: 30 / 80MALED Display: 0.36 incheColor: red highlightsThe driver IC is TM1637, only two signal lines can make MCU control four Digit 8-segment LED. Pinout: LED Display module to Arduino GND—ground (GND)VCC--power supply (5V)DIO--data input and output (D2)CLK--clock signal pin (D3)

Review: They work great, an easy to use Arduino lib drives them. - Nice and bright, but not over-driven, good size and a fantastic price. Only minor issue is that they soldered the four-pin connectors on the wrong side, making removal required if you want to actually mount these to a panel. Be sure to bring your desoldering skills.
Review: Great little display, but NOT I2C, and NO decimal points - It has the 4 pin I2C interface, but the chip has no slave addressing, so you can't put more than one display on an I2C channel. It does have a colon, if you want to display time, but NO DECIMALS. All five of my units came up out of the box, the library works great.

### ⭐⭐⭐⭐⭐ Great little display, but NOT I2C, and NO decimal points

### ⭐⭐⭐⭐⭐ Great value, works well
*by K***N on January 9, 2025*

I got a pack of five for just eight dollars, which is a great price. These things can get really bright, so I use them at the minimum brightness. As others have mentioned, there is one flaw: the headers are soldered at an odd 45 degree angle on the face side, so they will most likely require re-soldering if you want to panel mount them.
